Where did she get the Y-Chromosomes?

[irishjuggler]

It’s different in komodo dragons. Females have W and Z chromosome. Males have two Zs. If mom produces two Z gametes, which she can, and they merge, voila... ZZ = male offspring.

[Rockingham]

Different system for Komodo Dragons. Parthogenic offspring are all males.

Where did she get the Y-Chromosomes?

---

Don’t know if dragons to the XY thing or the ZW thing. And temperature can have a role as well. If it is true parthenogenesis, the offsprings should be genetic clones of mom.

[Kriggerel]

Reptiles don’t have a Y Chromosome. Or an X for that matter. It’s a different setup, like with birds. They have W and Z chromosomes.
